Physics QUESTION #7028

A force acts on an object of mass $2\text{ kg}$ such that its position as a function of time is $x = 3t^2 + 5$. Calculate the work performed by this force during the first $5$ seconds of motion.

$850\text{ J}$
$950\text{ J}$
$875\text{ J}$
$900\text{ J}$✔️

Correct Answer Logic:

Work done is equal to the change in kinetic energy ($\Delta KE$). First, find velocity $v = \frac{dx}{dt} = 6t$. At $t=0$, $v_i = 0$. At $t=5$, $v_f = 6(5) = 30\text{ m/s}$. $\Delta KE = \frac{1}{2}m(v_f^2 - v_i^2) = \frac{1}{2}(2)(30^2 - 0) = 900\text{ J}$.

Mathematics QUESTION #7469

Question 2443

For any $\theta \in (\frac{\pi}{4}, \frac{\pi}{2})$, the expression $3(\sin\theta - \cos\theta)^4 + 6(\sin\theta + \cos\theta)^2 + 4\sin^6\theta$ equals:

13 - 4cos²θ + 6sin²θcos²θ✔️
13 - 4cos⁶θ
13 - 4cos²θ + 6cos⁴θ
13 - 4cos⁴θ + 2sin²θcos²θ

Correct Answer Logic:

Expanding each term: $(\sin\theta-\cos\theta)^4 = \sin^4\theta - 4\sin^3\theta\cos\theta + 6\sin^2\theta\cos^2\theta - 4\sin\theta\cos^3\theta + \cos^4\theta$, $(\sin\theta+\cos\theta)^2 = \sin^2\theta + 2\sin\theta\cos\theta + \cos^2\theta = 1 + 2\sin\theta\cos\theta$. Combining and simplifying using $\sin^2\theta + \cos^2\theta = 1$ and algebraic manipulation gives: $13 - 4\cos^2\theta + 6\sin^2\theta\cos^2\theta$.

Chemistry QUESTION #5523

Question 2447

Identify the reaction that is NOT part of the ozone layer depletion mechanism in the stratosphere.

$CF_2Cl_2(g) \xrightarrow{hv} \cdot Cl(g) + \cdot CF_2Cl(g)$
$Cl\dot{O}(g) + O(g) \rightarrow \cdot Cl(g) + O_2(g)$
$CH_4 + 2O_3 \rightarrow 3\,CH_2{=}O + 3H_2O$✔️
$HOCl(g) \xrightarrow{hv} \cdot OH(g) + \cdot Cl(g)$

Correct Answer Logic:

The ozone depletion cycle involves: (A) CFCs releasing Cl radicals under UV, (B) ClO reacting with O atom to regenerate Cl radical (chain propagation), (D) HOCl photolysis to give OH and Cl radicals — all are real steps. Option (C), the reaction of $CH_4$ with $O_3$ to give formaldehyde and water, is NOT a recognized step in stratospheric ozone depletion chemistry.

Accounting & Finance QUESTION #6125

Question 2451

Sales $800,000; Variable costs $480,000; Fixed costs $280,000. What sales revenue is required for a profit of $200,000?

$520,000
$960,000
$1,000,000✔️
$1,200,000

Correct Answer Logic:

Option C ($1,000,000) is correct.

CS ratio = ($800,000 − $480,000) ÷ $800,000 = 40%

Required sales = (Fixed costs + Target profit) ÷ CS ratio = ($280,000 + $200,000) ÷ 0.40 = $1,000,000

Biology QUESTION #7237

Question 2452

The thalloid body of a slime mould (Myxomycetes) is known as:

Fruiting body
Mycelium
Protonema
Plasmodium✔️

Correct Answer Logic:

In slime moulds (Myxomycetes), the vegetative body is a plasmodium — a multinucleate, acellular mass of protoplasm that moves and engulfs food. It is not a true mycelium (fungal hyphae network) nor a protonema (moss juvenile stage).

Physics QUESTION #7337

Question 2453

A particle has initial velocity $(3\hat{i}+4\hat{j})$ and acceleration $(0.4\hat{i}+0.3\hat{j})$. Its speed after 10 s is:

10 units
7 units
$7\sqrt{2}$ units✔️
8.5 units

Correct Answer Logic:

Velocity at $t = 10\text{ s}$:

$\vec{v} = (3+0.4\times10)\hat{i} + (4+0.3\times10)\hat{j} = 7\hat{i}+7\hat{j}$

Speed $= \sqrt{7^2+7^2} = \sqrt{98} = \mathbf{7\sqrt{2}}$ units

Economics QUESTION #1697

Question 2454

Automatic stabilisers — mechanisms that automatically moderate economic fluctuations without requiring new legislative action — are instruments of which branch of economic policy?

Monetary policy
Trade policy
Fiscal policy✔️
Investment policy

Correct Answer Logic:

Automatic stabilisers are built-in features of the fiscal system (taxation and government spending) that automatically moderate business cycle fluctuations. Examples include progressive income taxes (tax revenues fall automatically in recessions, reducing the tax burden) and unemployment benefits (government spending automatically rises in downturns, supporting demand). They are fiscal policy tools — not monetary, trade, or investment policy instruments.
